The former inspector, who has not been named, was accused of contacting Surrey Police before they quizzed the ex-BBC star in 2009 over allegations of sexual offences.

The Independent Police Complaints Commission (IPCC) tonight said the officer has "no case to answer".

An IPCC spokesman said: "An IPCC investigation has concluded that a former West Yorkshire Police officer has no case to answer over allegations that he 'acted on behalf' of Jimmy Savile by inappropriately contacting Surrey Police ahead of a police interview in 2009."

West Yorkshire Police was ordered by the IPCC in 2013 to refer the conduct of the officer.
